Question About BMI

He also reminds me that BMI is not an accurate measure of total body composition. 😊

This is true. A weight lifter (or those with similar muscular builds may well show as being overweight by scales and BMI but in fact have a very low body fat percentage.

A DEXA scan is a one of the more accurate measures to determine body fat percentage vs lean body mass.

Your high blood pressure may well be related to genetics.

Ohhhh I don't like him already. He seems like the type that tells everyone to just lose weight as a solution for anything. He clearly didn't spend the 5mins to look over your medical history too. Wow

I would consider another PCP as well. This one is obviously not knowledgeable about WLS. People who've lost large amounts of weight often have heavier bones and muscles than those folks who've never been obese. You needed that extra infrastructure to hold up all that weight. You do lose some of it as you lose weight (along with the fat), but you're going to have more of it than someone who's always been normal weight (excess skin is also extra weight (maybe five lbs or so), but you've had that removed). The PA at my bariatric clinic said you'll probably look about 10 lbs lighter than what the scale says, because of the extra bone and muscle weight you have.

plus as others have said, why in the h*ll is this PCP complaining about you having a 28 or 29 BMI, when you've lost a ton of weight? They should be overjoyed. They must not be aware of your past medical records (??)

you have no idea how comforting this is for me. I do look much smaller than the scale says I should be (I have a BMI of 22 and keep getting these "you're too thin" comments from family members and even my husband at times). This actually makes it make more sense and helps a lot with some of the dysmorphic feelings I've had.

Another vote in favor of a new doctor. He seems like the type who's going to default to "lose weight" as the answer to anything and you don't want to find yourself six months into fighting him to get him to take some seriously while he's insisting you just need to lose weight to fix your compound fracture.

If you've never seen this video, I found it to be a really great explanation for why the best weight for a bariatric patient will almost never be the "ideal" weight according to the BMI chart:

Thank you so much for posting this! Wow. What a knowledgeable bariatric surgeon. He even said 27-29 for BMI. I really appreciated hearing him explain that ‘ideal weight’ is sometimes just not the goal for us bariatric folks. At a BMI of under 25, I think personally I would look sickly.

The BMI is a flawed guide, with "guide" being the operative word. I'm *JUST* in the "normal BMI" range now, and I'm a US6-8/AU10-12, at 5 foot 7 inches. My collarbone, neck tendons, chest bones all stick out, I can see my ribs, my muscles and tendons in my arms etc. I can even see my hip bones through the loose skin. I look skinny - I know I do, because I get a shock every time I see my full-body reflection, and I've been called skinny by others. But my BMI and the Hip/Waist ratio markers all suggest I'm not. My Hip/Waist ratio tells me I'm still quite overweight! It really doesn't take body shape into account as I've never had an hourglass figure - I joke that I'm shaped like a plank with tits. Straight up and down.

So don't take the BMI to heart, and I think it would be a good idea to tell this doctor your history. Some doctors don't think beyond their charts, unfortunately.

There are a lot of variables to consider. IMO, BMI is flawed....the formula is based on an average body composition. It does not take in consideration frame size, bone mass, muscle mass, large breasted vs small breasted (boobs are heavy!), body shape (ectomorph, mesomorph & endomorph). If you were overweight in your youth and/or the majority of your life, your bones had to accommodate more weight so therefore are most likely larger and heavier than someone who has been slim most of their lives.

Thirty years ago, the general rule for women was a baseline of 100 pounds for a 5 foot woman and 5 pounds for each additional inch. That is an average, but for me at 5'5", I am chubby at 125, where as; my daughter at 2 inches shorter, looks amazing at 135. Before the weight gain in 2012, my natural shape was hourglass (metomorph) with broad shoulders, heavy chested, small waist and slim legs on a small/medium frame. My daughter is rectangular (ectomorph) with broad shoulders, heavy chested, thick waisted, narrow hipped and thicker legs on a medium/large frame. My best weight is 112 to 117 but my daughter, even though she is 2 inches shorter, looks best at 132 to 138. "It really doesn't take body shape into account as I've never had an hourglass figure - I joke that I'm shaped like a plank with tits. Straight up and down." YES, YES, YES! The variations in the natural body composition of ectomorph, mesomorph or endomorph is not considered when computing BMI. An hourglass shape will carry more fat than a plank shape at the same weight!

Weight is a personal matter. You have to find where you are comfortable and a weight that can be easily maintained. Listen to your body and listen to your doctor but don't let others get into your head.

Good Morning:

I just wanted to get some feedback in case anyone else has experienced this (I'm quite sure some have). My last bariatric follow-up was fine. He told me my numbers were good and to keep it up. This week, I had a visit with my new primary care doctor. My previous PCP retired after 15 years (which I was very sad about-her retirement was unexpected). I was with her before & after my RNY, and she was very knowledgeable about everything related to the surgery.

When I went to the new PCP this week, after he reviewed my numbers (BP was a little high-I was told to stop taking my birth control because it can cause high blood pressure for woman over 35), he looked at my weight and advised me to lose more weight, which could help with my BP. I wanted to go on the defensive but did not. My BMI stays around 28-29, and that is after having skin removal on my entire body. I wear size 6-8 jeans and small to medium in pants. I honestly don't know where the additional weight could be lost lol.

My question is: how does everyone else handle this with a medical provider when it's encountered? I wanted to tell him that I used to weigh 311 pounds, so my weight now is considerably better.

I would go ahead and see if you can get a second opinion and I would seriously tell him what you did weigh, and keep it up

      195 weight when I went in for surgery
      199 weight when I got home for surgery
      193.2 weight 4 days after surgery
      If the inflammation from surgery is resolved, I've lost 1.8lbs in 4 days.

      Had surgery last Thursday, so I've been home for 2 days as of 15 minutes ago.  I weighed more when I got discharged than when I went in despite only having eaten a Jello cup in 2 days, but I put that down to inflammation. This morning I weighed a little less than I went in.  I sneezed last night and my fiance saw me cry for the first time, and we've been together 16 years. I took my multivitamin first thing this morning and threw up. Kept it down after drinking 4oz protein shake. Yogurt gives me diarrhea, water hurts more than the fuller liquids, and my stomach is turning somersaults and I think I'm hungry because I'm used to interpreting it that way, but I have no desire to eat.
      My biggest problem is that I am used to being busy.  I own a business and I've been getting active on these boards, and when I'm on my laptop I forget to drink. Will I hurt myself if I drink faster?  I've been scheduling 4oz every 30 minutes with breaks before and after meals.  Is it too fast to drink 4 oz in 15 min to get caught up on what I missed?

      tl:dr at bottom,
      I could use some advice. I went to see my dietician today (not a bariatric surgery dietician, I can explain why I am seeing her if you want to know). She knows I am going to have weight loss surgery as long as I hit the goal weight my insurance told me I need to be at. I have to be at the goal weight by June 24, 2023, in order for my insurance to pay for my surgery.
      I had a weigh in the doctor's office a couple of days ago and weighed 301, my scale at home said 302. However, on the same day, the scale at a friend's house said 313. 
      I knew I had this Dietician appointment two days later and I knew she would weigh me. I continued to weigh myself at home (after getting new batteries) and I was at 302 then 299 and today at home I weighed 303, right before my appointment, when I got to her office I was weighed and it said 313.
      I am concerned about what to believe since the doctor's office and my scale show similar numbers. I also bought a new scale today and it said 313. 
      The Dietician told me I needed to eat more protein, which honestly I struggle with. she said I needed 150 grams!!  I said are you kidding? that seems like a lot.  She used my weight to come up with this number. 
      Should I really be trying to eat enough protein for a 300-lb person or should I be eating protein for a goal-weight person (mine is 170)?   
      also, my clothing is loose like I lost the 20 lbs mine and the doctor's scale shows, and not 10 lbs like everyone else's scale shows. Also, I have always naturally been more muscular even when I was 120 lbs and did not eat any protein aside from what is in plants. 
      tl:dr- should I be eating enough protein to support a 300lb person or should I be eating protein for a "normal" sized person? AND should I trust the Doctors scale more so than the Dietician's scale?

        I had the same issue. My scale was 6 pounds heavier than my bariatric doctor's. My scale agreed with my nutritionist's scale. I asked my bariatric doctor to have her scale recalibrated and she said it was a really expensive scale, so she trusted it. So, when it comes down to it, the scale that matters isn't the one that's right, it's the one that determines if you get your surgery or not. I would ask her when it was last calibrated and see if she will calibrate it. The difference is I Iost weight so well on the lifestyle change diet that I had to stop losing weight or risk not getting the surgery.
